I'm guessing you've read the Court of Inquiry on this? Problems with the laminates were known issues with Mosquitoes, particularly in the tropics. There is one record of sabotage of the glue used in the laminates. It's a fighter combat aircraft, deigned for violent manoeuvres at speed. The pilot a decorated Battle of Britain Pilot, probably with a couple of thousand hours Flying time, and trained prewar. My point is that the Mosquito had known issues.
Sorry! I was lazy and lifted this out of Wikipedia:
de Havilland Mosquito - Wikipedia
"In November 1944, several crashes occurred in the
Far East. At first, these were thought to be a result of wing-structure failures. The casein glue, it was said, cracked when exposed to extreme heat and/or monsoon conditions. This caused the upper surfaces to "lift" from the main spar. An investigating team led by Major
Hereward de Havilland travelled to India and produced a report in early December 1944 stating, "the accidents were not caused by the deterioration of the glue, but by shrinkage of the airframe during the wet monsoon season".
[nb 15] However, a later inquiry by Cabot & Myers firmly attributed the accidents to faulty manufacture and this was confirmed by a further investigation team by the Ministry of Aircraft Production at
Defford, which found faults in six Mosquito marks (all built at de Havilland's Hatfield and Leavesden plants). The defects were similar, and none of the aircraft had been exposed to monsoon conditions or termite attack.[

The investigators concluded that construction defects occurred at the two plants. They found that the "... standard of glueing...left much to be desired."
[88][89] Records at the time showed that accidents caused by "loss of control" were three times more frequent on Mosquitos than on any other type of aircraft. The Air Ministry forestalled any loss of confidence in the Mosquito by holding to Major de Havilland's initial investigation in India that the accidents were caused "largely by climate"
[90] To solve the problem of seepage into the interior, a strip of plywood was set along the span of the wing to seal the entire length of the skin joint.
